 "description": "Host Studio is a high-performance, native 3270 and 5250 terminal emulator engineered for macOS, iOS, iPadOS, and Apple Vision Pro. Connect securely to IBM mainframes (z/OS, z/VM, z/VSE) and IBM i midrange systems (AS/400) with authentic CRT rendering, stream-to-native GUI transformation, IND$FILE dataset transfer, virtual SCS host printing, and enterprise MDM fleet management.\n\nAUTHENTIC TN3270E & TN5250E EMULATION\n• TN3270 & TN3270E Engine: Full RFC 2355 negotiation, LU pooling, and Screen Models 2, 3, 4, and 5 (27×132).\n• TN5250 & TN5250E Engine: Connect to IBM i (AS/400) via RFC 1205 & RFC 4777 with 24×80 and 27×132 displays, Workstation ID allocation, automated bypass sign-on, associated printer binding, System Request, and menus.\n• EBCDIC Code Pages: Native mapping for CP037, CP273, CP280, CP284, CP285, CP297, CP500, CP870, CP871, CP930, CP1047, and more.\n• CRT Theme Gallery: Green Phosphor, Amber Classic, Crisp Paper White, Cyberpunk, and High Contrast presets with scanlines, OIA status line, and 3279 colors.\n\nSTREAM-TO-NATIVE UI CONVERSION\n• Instant GUI Mode: Switch between CRT terminal view and modern SwiftUI forms with a single tap.\n• Subsystem-Aware Parsing: Automated detection for IBM CICS, z/OS TSO/ISPF, IBM IMS, and z/VSE.\n• AS/400 Subfile Grids: Parses IBM i subfiles (WRKACTJOB, WRKSPLF) into interactive tables with option inputs and status indicators.\n• Clean Labeled Forms: Strips filler dots and prompt leaders into clean inputs and structured key-value cards.\n• Interactive Command Bar: Extends primary command and option prompts (Option ===>, TRANID) into an ergonomic command bar.\n• Contextual Action Buttons: Automatically extracts screen PF/PA legends into native action buttons.\n\nBIOMETRIC SECURITY & KEYCHAIN PROTECTION\n• Face ID & Touch ID Session Locking: Protect sensitive host bookmarks behind biometric authentication before connecting.\n• iCloud Keychain Credential Sync: Sync host credentials securely across your Apple devices via the encrypted Apple Keychain.\n• Sanitized Bookmark Sharing: Safely export and share host bookmarks via AirDrop or JSON with credentials automatically stripped.\n\nENTERPRISE MDM & FLEET MANAGEMENT\n• Managed App Configuration: Deploy pre-configured corporate bookmarks, enforce TLS encryption, and lock settings via Apple Business Manager and MDM (Jamf, Microsoft Intune, Workspace ONE).\n• Data Loss Prevention (DLP): Restrict host dataset downloads and local file exports via centralized MDM policy.\n\n5250 VIRTUAL SCS PRINTER & SPOOL WORKBENCH\n• Real-Time Spool Capture: Emulate a 5250 companion printer (RFC 2877 / RFC 4777) to capture IBM i print jobs in real time.\n• Vector PDF Generation: Converts SNA Character String spool data into crisp vector PDFs.\n• Spool Job Management: Inspect, export, share, or print host reports wirelessly via AirPrint or macOS CUPS.\n\nIND$FILE MAINFRAME DATASET TRANSFER\n• Multi-System Support: High-speed transfers with TSO/E, VM/CMS, and CICS subsystems.\n• Structured Field & CUT Modes: Full support for Outbound/Inbound Structured Fields and CUT transfers.\n• Flexible Formats: Handles Fixed (F), Variable (V), and Undefined (U) records with configurable LRECL, BLKSIZE, and ASCII/EBCDIC/Binary modes.\n\nAPPLE ECOSYSTEM INTEGRATION\n• Spotlight Search: Search host bookmarks in system Spotlight for instant launch.\n• Siri Voice Shortcuts: Ask Siri to connect to saved host sessions hands-free.\n• Tabletop & DuoPosture Console: Ergonomic split layout with tactile keypad and navigation D-pad.\n• Barcode & Camera Scanner: Scan physical barcodes and QR codes directly into host input fields.\n• Session Safeguards: Prevents accidental disconnects on quit (⌘Q) or window close during active sessions.\n\nZERO-NETWORK OFFLINE DEMOS\nTest drive IBM 3270 and IBM i (AS/400) TN5250E emulation, Native UI conversion, themes, printer spools, and navigation immediately upon launch with built-in dual offline demo sessions.",
